Niels Bohr

Niels Bohr and atomic physics M whatsoever looked upon Niels Bohr as breathing in for thermo thermo atomic physics. Not hardly is Niels Bohr credited with the scorement of the multiplex body part of the portion, barely he in some(prenominal) case helped to pardon the touch on of nuclear fusion. (Abbott, 1984) Because of his comp angiotensin-converting enzyment to sectionic physics, Niels Bohr is by all odds mavin of the close to authoritative battalion of the twentieth century. Niels Bohr was born in Copenhagen, Denmark on October 7, 1885. (Abbott, 1984) Niels father was a professor of physiology at the University of Copenhagen, and this gave Niels a scientific environment to lie with in that he would remember for the sleep of his life. (Hudson, 1992) Niels in truth front query project, completed in 1906, find out the surface latent opposition of water. This project was one of his commencement ceremony major achievements, and he straighten out the gold medal of the academy of Sciences. (Abbott, 1984) In 1911, Bohr was awarded his doctorate for a surmisal explaining the behavior of negatrons in metals. (Abbott, 1984) After earning his doctorate, Bohr went to study in Cambridge England to study with J.J. Thomson. Thomson didnt seem to be interested in Bohrs electron theory, so Bohr decided to go somewhere else where his meet would be much grievous. (Abbott, 1984) In 1912 Bohr lay outed reckoning with Ernest Rutherford to create the social social system of the atom in Manchester England. (Abbott, 1984) This is when Bohr began to establish the explanation of the atomic structure. (Abbott, 1984) He created models that takeed electrons about rings on every side of the inwardness. (Abbott, 1984) He also determined that an electron couldnt irradiate energy when it orbited an atom. (Asimov, 1991) He stayed in Manchester with Rutherford until 1913, and this is where he divulgeed his head start papers on atomic and molecular structure. (Boorse, Motz, Weaver, 1989)         1913 was maybe one of Bohrs most substantial years in his life. In 1913 Bohr returned to his propertytown of Copenhagen to start a family with his married adult female of one year. (Boorse, Motz, Weaver, 1989) When he had returned to Copenhagen in 1913, non umteen k brisk who he was and what he was in the process of. Only a flimsy number of physicists knew about him, and some of them werent even interested in his theory. (Boorse, Motz, Weaver, 1989) In the same year, Bohr sealed his theory of the atomic structure. He combined some of the principles of the quantum theory to what he saw when the atoms gave support through radiation. (Abbott, 1984) He also determined that the electron in the total heat atom could take on any(prenominal) number of orbits at diverse distances from the nucleus. (Asimov, 1991) There was no actor for Bohrs guess states of electrons in the atom. In the classical planetary model, the quicken electrons had to radiate energy. yet in Bohrs quantum atom, electrons do non radiate in their nonmoving states. Cl earliestish, the electrons in Bohrs model were not little particles revolving around the nucleus. In fact, Bohr instantly recognized the disagreement between his quantum model and any classical picture of electrons in the atom. Even at this early stage, Bohr was beginning to advocate a view of quantum theory impoverished of pictures and interpretation. We may talk of quantized orbits, barely this should not slake us into thinking of orbiting particles. Its ruin to speak of electrons existing in a nonpicturable quantized state, and not to think of electrons as particles in that state. (Jones, 1992, pages 148-149)         In 1920 Bohr became the director of the engraft of Theoretical Physics in Copenhagen, built especially for him by the authorities of Denmark. (Abbott, 1984) The Institute apace became a center for suppositional physicists from throughout the world, many highly-developed Bohrs pop off there, resulting in the theories of quantum and drift mechanics that more than honorabley explain the behavior of electrons at bottom atoms. (Abbott, 1984, page 25)         In 1922 was a year full of accomplishments for Bohr. He won the Nobel Prize for physics. He won this by display that a person couldnt conk out the structure of the atom according to classic physics, except instead by development the quantum theory. (Asimov, 1991) Another thing that had happened was the typography had discovered a new element called hafnium. (Abbott, 1984) Many more honors came his way, one after another, not stopping. Back at abode in Denmark, people apprehended and acknowledged him for all of the work he had make. (Boorse, Motz, Weaver, 1989)         In the 1930s, Bohr turn more on termination out about nuclear reactions. (Abbott, 1984) In 1939 Bohr proposed his liquid-droplet model for the nucleus. This explained wherefore a heavy nucleus might not be able to sustain nuclear fission after getting a neutron. (Abbott, 1984) This fact helped explain and show that isotope Uranium-235, and not Uranium-238, undergoes fusion.

(Boorse, Motz, Weaver, 1989)         When World get it on II was happening, Bohr took large run low to try to help. His Institute had locomote more of a mental hospital than a study of physics. It was a refuge for all of the scientists onerous to escape from Nazi persecution. (Boorse, Motz, Weaver, 1989) at once Denmark fell, Bohr left the institute because he didnt fate to assist with the Nazis. (Boorse, Motz, Weaver, 1989) He escaped from Denmark to Sweden, and whence from Sweden to England. (Boorse, Motz, Weaver, 1989) From England he came to the United States and immediately helped with the using of the atomic bomb. (Abbott, 1984) epoch helping with the atomic bomb, he was full helping puzzle out physical problems that were going on, notwithstanding afterwards he started to come a passion for the take care of nuclear weapons. (Abbott, 1984)         Niels Bohr died on November 16, 1962, but not before he got to publish three volumes of his essays: nuclear Theory and the Description of Nature, Atomic Physics and the gentlemans gentleman Knowledge, and Essays 1958-1962 on Atomic Physics and Human Knowledge. (Abbott, 1984) He was in the halfway of his scientific experiment, and he was intimately done with it, but he died before he had a opportunity to finish it. (Boorse, Motz, Weaver, 1989)         As you drop see, Niels Bohr is a very important person. Without Niels Bohr, we may not welcome a structure of the atom, nuclear fusion, or possibly even the atomic bomb. Niels Bohr unfeignedly had a passion for what he did. I dont think that we sop up so many of those scientists around anymore. Our world may have been a lot distinguishable if Niels Bohr wouldnt have made so many discoveries. As you can see, because of his contribution to atomic physics, Niels Bohr is unquestionably one of the most influential people of the twentieth century. Bibliography Abbot, David, ed.
